CarPlay
In the last two weeks MBUX has not recognized wireless Apple CarPlay multiple times. When the car is unable to connect to CarPlay, I immediately drop and re-add my iPhone if I need CarPlay. Otherwise, I wait and a day or a few days later CarPlay starts working again. After re-adding the device it seems like it works for about a month before the problem returns.
This time, MBUX stopped recognizing wireless CarPlay a day after the reset. It even stopped recognizing wired CarPlay which is extremely unusual. I was going to drop and re-add CarPlay, but mysteriously wireless CarPlay started working today without me making any changes. Even more unusual, on one drive today, it didn’t recognize CarPlay at first, then it found it, then lost it, then found it again. I haven’t seen that behavior before. In the past, for a single drive, it either saw CarPlay upon startup or didn’t see it at all during the drive.
I am on software version E333.8-58.
Has anyone figured out why the car usually connects to CarPlay, but then sometimes it doesn’t?

Unfortunately I have no solution for you but wanted to let you know I regularly experience this same CarPlay recognition inconsistency. It is annoying. I have discovered that around 80% or more of the time when it says it doesn’t recognize or cannot connect I simply have to press the Apple Carplay label in the upper left corner of the Home Screen and CarPlay appears near instantly despite the failed to connect message.

I had the same problems with CarPlay -- sometimes it would connect, sometimes it wouldn't, other times it would connect and then stop working... and then start working... etc. I also tried removing and adding the device, but it didn't help. The phone works fine with everything else, including my spouses' Honda.
Well, the good news is that the update for the recall -- E354.2-4221 -- done by the dealer seemed to have fixed it. At least, I haven't had any issues since the update.

I had the same issue. I ended up doing a full reset and it's worked flawlessly since then. But, you will lose all your current settings and have to set everything back up again. It was a PITA, but Car Play working when it wanted to was worse.

I've intermittently experienced this connection error. Oddly enough, after getting past the error notification I'll see Carplay available in the upper left of the center screen...tapping there brings its it up as if no issue had occurred.

This occurs to me at least once a week...I drive my CLE 53 just about everyday. What I do is click device manager (the two small iphones icon under the big Phone icon). Once device manager is display the carplay icon is white, just click on it. quicker then pairing phone again.

no vpn on phone for me. Today, I replied to a text via applecarplay and after it sent my entire carplay screen went blank...meaning no icons just blue background. I went to the MBUX screen. Apple carplay was still conneced but clicking on he words applecarplay on the upper left did nothing.
I had to run an errand 15min later and all fine now - meaning shutdown and restart.

When this happened to me, deleting and reconnecting carplay didn’t work. What fixed it was shutting down the phone and turning it back on again.
so um, try turning it off and on again

There are many people who have reported intermittent issues with connection using iPhone. It is variably present, has been around for years, is based on some flaw in Apple software, and it doesn't look like there is a known cause or solution. Turning the phone on and off usually allows connection, but not always.
